Great question! This type of question begs more research so we can use the
information to improve our fishing.

The responses to your question so far vary widely. Here is more info.

My family has three ponds raising fish commercially. They keep accurate
numbers for each year by pond and by fish type. Previously they raised
Golden Shiners for bait and now they raise catfish. Each year all ponds are
drained to a low level and each pond is seined to completely remove all
fish. Then the ponds are poisoned and then restocked with fingerlings.

Each year yield in total pounds per pond may vary as much as 50% above or
below prior years. Wet summers produce more fish than dry summers but not
always in all ponds. Furthermore one pond may vary 50% while another pond
is essentially the same as the prior year. They use no fertilizer. All
ponds are used to water stock year around. The 50% variance applied both to
the catfish and also the shiners. Barriers keep fish from moving between
ponds or up into or down into any pond. Essentially the same measures are
taken against predators each year.

Why so much variance? We don't know. We need more research to understand
fish per acre!

Anyone have a handle on how many adult bass (12"+) there are per acre in
an
average lake?
